Wikipedia:List of protected pages/User pages

Protected user pages
User pages sometimes become targets for vandalism, and may be protected upon request of the user associated with the page if this is a serious problem. Clear evidence can be seen from a user's history of the page, and their history from their discussion page.

By software configuration, script files (*.js) and stylesheets (*.css) in user spaces are protected such that only the user or an administrator can edit it.

User talk pages: Registered users
'''User talk pages should only be protected in cases of persistent vandalism, and then only for as brief a period as possible. Please use the template Usertalk-sprotect to mark such pages. This adds the page to Category:Semi-protected user and user talk pages.''' If the vandalism is by the user himself/herself, use the vandal tag; otherwise, use the article tag. For blocked or banned users, use ProtectBU.

User talk pages: Anonymous users
'''Talk pages of anonymous users should generally only be semi-protected. This prevents a vandal from blanking warnings etc., but still allows non-admin RC patrollers to issue warnings on this page. Please use the template Usertalk-sprotect to mark such pages. This adds the page to Category:Semi-protected user and user talk pages.''' Please use the IPvandal tag (replacing " " with "_" as appropriate). Admins, please remember to check back periodically and unprotect talk pages as blocks expire.

Protected user subpages and boilerplates
Some users have created boilerplate pages in their user namespace and protected them from editing.
